I need help URGENTLY!!

Do آپ not want to leave your old school purely because آپ don't want to leave your friends, یا because آپ believe your old school is academically better for آپ then the private one?
Either way, آپ must be smart to be accepted right away, and i don't think this is a chance آپ should miss. Private schools have so much مزید to offer then public as they get مزید funding etc, so perhaps you're dream job will become reality thanks to آپ going to this private school?
You'll make دوستوں again at this school, so i wouldn't worry about it too much, and although leaving old دوستوں behind is heart-breaking it's not forever. Even if آپ are unable to see your old school دوستوں out of school, there are still phones, letters and e-mails and even instant messenger where آپ can catch up on all the gossip, and during breaks in the school semester. summer holidays, weekends even, آپ can ask to meet up at the shopping centre یا a cafe and see them then.
I wouldn't worry about it too much :) People اقدام on all the time, there's nothing scary about it once آپ get used to it.

OK, One thing to remember it wont be forever. آپ will make دوستوں and its a new chapter in your life and آپ dont know until آپ try if آپ will like it. Once آپ settle in آپ will be fine. Hope that helps.

Watch this and آپ will forget about it right away :)

Hmm thats tough. Well, there is not much آپ can do apart from keep in close contact with your friends, cause thats what really makes a school, and try to make the best of your new situation instead of being miserable and working against it.
